and hasfor its principal object to produce a foldable" st ucture whichis simple and inexpensive, yet strong and durable, which may be readilyopened as a full size bed and folded compactly into a small space toconstitute a sofa or divan.

It further object is to produce a structure wherein the pivotal framesections are Well balanced so that the Weightand leverage are equalizedthroughout the opening and closing movements thereof.

()ther advantages hereinafter more fully appear.

The invention consists in the parts and in the arrangements andcombinations of parts hereinafter described and claimed.

in the accompanying drawings which form part of this specification andwherein like svmbols refer to like parts Whereverthey occur,-Figure 1 isa side elevation of the device folded as a sofa or divan; Fig. is a sideelevation showing the device par tially opened; and Fig. 3 is a sideelevation of the device fullyopened as a bedstead.

The device comprises a supporting frame comprising vertical front andrear corner members 1 and 2, respectively. The lower portions of themembers 1 and 2 are connected by said members 1 and 2 are respectivelyconnected to the member 3 by diagonal braces 1 and 5. The verticalmembers 1 and 2 are respectively connected near their lower ends byfront and rear cross members 6' and 7 3 and, obviously, diagonal bracesor stays 5 similar to those t and 5 above noted, may connect saidmembers 2 with their cross member 7. The rear vertical corner members 2are extended up as at 2 near their upper ends by a cross member 8. Theextensions 2 and cross members 8 serve as a head-board and also asupport for the folding outer frame section (hereinafter described) whenit is in closed position.

Pivotally supported on the front vertical corner members 1 is areversible frame comhorizontal end members 3: and

and connected prising triangular end members 9, 10 and 11. The members1.0 and 11 are res ectively connected by cross members 12 an 13 and theymay be suitably. braced by diagonal stays12 and 13 similar to thosed and5 above set forth. The

versible frame are pivoted, as at 14310 brackets 14 secured to the frontvertical of the members 11. The end portions 10 pivotal frame members 10are extended some distance beyond the members 9 and are pivotallyconnected, as at 15, to extensions 15 of end members 15 of a cooperati'nframe Whose other end members 16 and 1% are connected to said members 15in triangular relation. Across member 18 connects the res ective endframe members at or about t e juncture of the members 15 and by diagonalstays 18 bers 16 are extended some distance beyond the point of juncturewith the members 17 and are pivotally connected to the upper endportions of supporting links 19, as at 19*. The links 19 are pivotallyconnected at their lower e1 1 v as at 19, on brackets 20 secured on thelori'zontal end members 3 of the supporting frame. The members 9 of thereversible frame have their end portions 9 extended some distance beyondthe point of juncture with. the members 11 members 10 of the re 17 andis also connected to the members 1-5 I '75 The rear end portions 16 ofthe mem-' iind pivotally connected to extensions 21of end members 21 ofa second cotiperating folding frame, as at 21. The opposite end portionsof the members 21 are secured to members 22 constituting supporting legsfor the frame in its open position, as shown in Fig. The legs 22 andframe members 21. are connected by diagonal stays 23; and said legs 22are also connected by across member 24. The cross member 24 is alsoconnected to the legs 22 by diagonalstays or braces 24 and it is adaptedto rest on the ends 10 of the reversible frame members 10 when the frameis folded back into the position shown in Fig. 1. Members 25 and 26 aresecured to the members 21 of the folding frame and to each other intriangular relation; and said members 25 and 26 areconnected at theirpoint of juncture by a cross member 27 and the respective members 25 and26 are connected to said cross member 27 by dia onal stays or braces25?!1d 26. [The members 25 and 26 being r dly se- 1.10

curedto the members 21, and connected by the cross member 27 and bracedby the diagonal stays 25 and 26*, form ,a rigid cross tie and truss forthe outer folding frame; and the triangular end members 15, 16 and 17 ofthe other folding frame which cooperates with the reversible frame andare connected by the cross member 18, also serve to stiffen thestructure. It is also preferable to provide a cross member 16 endextensions 16 cent to the pivots 19% The lower end portions of the legs22 are connected by a cross tie piece 28 so as to resist the tension ofthe spring mattress support which is connected only to side framemembers 21 of the outer folding section, and its tendency is to draw theupper end portions of the legs inwardly. lower portions outwardly,iowing to the location of the cross memand force their ber 24.

The arrangement of-the triangular end: members 9, l0 and 11 and crossmembers 12 and 13 of the reversible frame gives considerable rigidity tothat structure; and it is necessarily required, for the reason that thisframe is really the main supporting frame,

while the two others are secondary or auxiliary frames.

The several supporting posts and frame members are preferablyconstructed of angle irons. This enables the structure to be made lightwithout sacrificing rigidity.

Arontinuous mattress 29 is employed, and it is supported on a suitablewoven wire fabric or other flexible spring mattress support, not shown,but which may be obviously secured to the horizontal flanges of the sideframe members members being arranged substantially the same horizontalplane, as shown-in Fig. 3. The structure also permits the frames to befolded with the mattress thereon into the position shown in Fig. 1, theportion of the mattress which is car- 16, 9 and 21, said so as to openin ried by the outer frame members21 serving as the cushion for the sofaseat.

position of the device, as shown in Fig. 1, the end extensions 21 of themembers 21 rest on the cross member 8 which connects the rear uprights 2of the stationary supporting frame, while the horizontal flange of thecross member 24 which connects the supporting legs- 22 rests on theupper end portions 10 of the reversible frame members 10.

In the closed The device may be easily opened to the.

position shown in Fig. 3 by merely lifting on the outer frame membersand drawing the same forward; and it is closed just as The inner bedsection being hinged on the supporting links 19 and pivoted to isbrought into posistructure is counterso that there are no sudden tion;and the Whole balanced,

'quired to be released prior to which connects the of the members 16adjachanges in weight and leverage which would require the personoperating the device, either in opening or closing the same, to exerciseany special caution. Nor is it necessary to provide any locking means orlatches to hold the device in either closed or open position, and,therefore, none are recfi'ecting the openlng and closing of the device.

Obviously, the device admits of considerable modification withoutdeparting from my invention. Therefore, I do not wish to be limited tothe specific construction and arrangement shown.

What I claim is:

1. A sofa-bedstead frame, a reversible intermediate frame mountedthereon, a mattress support on said intermediate frame, an outer framepivoted to said reversible frame in cooperative relation to one sidethereof, a mattress support on said outer frame constituting thecomprising a base sofa-seat, means for supporting said outer framehorizontally above said intermediate frame, an inner frame pivoted tosaid intermediate frame in cooperative relation to the side opposite tothat with which said outer frame cooperates, a mattress support on saidinner frame, and compensating means for supporting said inner frame onthe base frame in conjunction with said intermediate frame.

2. A sofa-bedstead comprising a supportmg base, a reversibleintermediate frame pivotally supported at its opposite ends on saidsupporting base, an inner frame movably mounted on said supporting baseand connected to said reversible intermediate frame in cooperativerelation to one side thereof and folded thereunder in its closedposition, and an outer frame connected to said reversible frame incooperative relation to the opposite side thereof and foldedhorizontally and supported thereon in its closed position, saidreversible intermediate frame having a mattress thereon and said innerand outer frames each having a mattress adapted to be moved in the samehorizontal plane with the mattress of said reversible frame in theiropened positions, the mattress on said outer frame constituting the sofaseat.

3. A sofa-bedstead comprising a base frame; a reversible intermediateframe having right triangular end members, one of said members at eachend being pivoted to the base frame, the hypotenuse members beingrespectively extended beyond the ends of the other angle members, saidpivoted angular members being respectively extended beyond the adjoiningends of said hypotenuse members; an inner frame having triangular endmembers, two of these members at each end being extended, the extensionofone memberbeing pivoted to her of the mtermediate frame an hypotenusethe extension of the adjacent angular memd the ex tenslon of the othermember being pivoted to a compensatmg supporting member on the baseframe; an outer frame having end members pivoted to the extensions ofthe members fire-me, locking therewith in open position;
